Description

Technical Field

[0001] The invention relates to the technical field of pile road cleaning devices, and in particular to a pre-bent pile road cleaning device and a working method thereof. Background Art

[0002] In recent years, with the development of bonding technology and dental materials, more restoration solutions have been provided for tooth defects in clinical practice. When the tooth defect is large and the remaining tooth tissue is insufficient to provide retention for the core and support the final restoration, the post in the root canal can be used to assist retention and perform post-core crown restoration. Among the materials of the post, the glass fiber post has been widely promoted and applied in clinical practice due to its beautiful color and elastic modulus close to dentin.

[0003] However, in clinical practice, fiber posts often fail to bond with the dentin of the post channel, leading to the final restoration failure. The bonding interface between the adhesive and the dentin of the inner wall of the post channel is the main factor affecting the bonding performance of the fiber post. Therefore, in order to obtain an ideal dentin bonding surface, the resin adhesive is fully bonded to the dentin surface of the inner wall of the post channel, and it is essential to clean the smear layer formed by sealers, gutta-percha, dentin debris, saliva, blood, etc. on the dentin surface after the post channel preparation.

[0004] The post channel preparation drill currently used in clinical practice is circular. For oval and other irregularly shaped root canals, the post channel preparation drill cannot reach the grooves in such root canals, resulting in sealers, gutta-percha, debris, etc. remaining in the narrow grooves after the post channel preparation, thereby reducing the effective bonding area and affecting the bonding effect between the fiber post and the dentin of the inner wall of the post channel. In addition, the flushing after the post channel preparation is mostly carried out by loading an organic solvent into a syringe, then inserting a flushing needle into the post channel to flush the post channel, or using an ultrasonic root canal washing ultrasonic working tip, using the cavitation effect of ultrasound to make the flushing liquid reach the inner wall of the post channel, and shaking off the smear layer on the post channel wall. Existing instruments all use the flushing method of flushing liquid to remove loose substances attached to the inner wall of the post channel, but cannot directly act on the smear layer on the inner wall of the post channel, and thoroughly clean the post channel through mechanical action, so the cleaning effect of the post channel dentin is not ideal. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a pre-bending device for cleaning root canal and a working method thereof. The device can select appropriate holes on the pre-bending ruler to pre-bend the ultrasonic working tip according to the depth and diameter of the root canal, and the pre-bent working tip is used for cleaning the elliptical root canal root canal.

[0009] Furthermore, an opening connected to the water tank is formed on the pointed body, and the end of the pointed body is a pointed head or a round head.

[0010] Furthermore, the connecting rod has a connecting cavity communicated with the water tank, the inner wall of the connecting cavity has an internal thread, and the connecting cavity is used to connect to an external water source connector.

[0011] Furthermore, an operating portion for a wrench to act on is provided on the connecting rod.

[0012] Furthermore, the water tank is connected to an external water source to form a wave flow between the pointed body and the pile channel to wash the inner wall of the pile channel.

[0013] Furthermore, the ruler body is provided with a plurality of groups of holes with different diameters, and the number of holes in each group is 5 to 10.

[0014] Furthermore, the ruler body is provided with four groups of holes with different diameters, and each group has seven holes.

[0015] Furthermore, the diameters of the four groups of holes are respectively D1 = 0.4 mm, D2 = 0.5 mm, D3 = 0.6 mm, and D4 = 0.7 mm.

[0016] Furthermore, the length of the pre-bent guide cylinder arranged below each group of holes gradually increases from one side to the other side.

[0017] Furthermore, the ultrasonic working tip is used for cleaning the elliptical root canal post channel.

[0018] The present invention also provides a working method of the above-mentioned device, selecting a matching hole on the pre-bending ruler according to the depth and diameter of the post channel, inserting the tip of the ultrasonic working tip into the pre-bending guide tube through the hole for pre-bending, and the pre-bent ultrasonic working tip is used for cleaning the elliptical root canal post channel.
